AQUANEAT Small Fountain Pump, 160 GPH Submersible Water Pump for Aquarium Fish Tank, Outdoor Water Fountain, Hydroponics, Pond Filter Pump

Adjustable flow rate: With a control knob, the maximal flow rate can be up to 160GPH(600L/H); Recommanded H-Max (Lift height): 2ft. Note: 160GPH is the theoretical flow rate at zero lift; the actual output decreases with pipe resistance, lifting height. And the higher the lifting height is, the lower the flow rate will be. For example, the flow rate is 160 GPH at 0 ft (without any water pipe), 90 GPH at 2 ft, and nearly 0 GPH at 3.6 ft. And the pump operates on the principle that higher lift results in lower flow rate.

Optional 2 outlets: Fits 5/16"or 1/2"ID (inside diameter) tubing

Dimension: 2.50" x 1.75" x 2" (L x W x H), mini size, easy to hide or disguise; Length of power cord: 6 feet

Wide application: Perfect for water fountains, pet fountain, aquariums, table fountains, waterfalls, hydroponic systems, irrigation systems and for use in any other water features.

Why is my pump not working properly? To ensure the water pump operates properly, the following steps must be taken: Submersion Requirement‌: The pump must be fully submerged in water. Debris Clearance: If the impeller is jammed by debris (e.g., fish waste, algae, gravel), causing the pump to stop working, disassemble the housing to remove obstructions and check pipe connections for kinks or blockages to resume normal operation. ‌Air Removal‌: For the first startup or after water replacement, gently shake the pump to expel any trapped air inside; air trapped in the pipe or the pump may cause "gurgling" noises and the pump failure due to airlock.

Package Includes: 1x 160 GPH Fountain Pump, 2x Outlet Adapters
